Question 5: (5 marks) Mediator is a protein complex that is able to act as a bridge between transcriptional activators and the TFIID-dependent RNA Pol II machinery. Draw what you would expect the promoter region to look like with Mediator acting at the promoter of a gene with an E-box 3000bp upstream of the transcriptional start site, which requires TCF4 for activation of transcription....

Identify the statements that are features of a promoter. Pick all that Apply. A. In eukaryotes, the promoter recruits the preinitiation complex, which includes the TATA-binding protein. b. In prokaryotes, the promoter is recognized by general transcription factors (GTF), which recruit the RNA polymerase holoenzyme. c. In eukaryotes, the promoter attracts the small and large ribosomal subunits with the help of initiation factors. d. In prokaryotes, the promoter contains a –35 and –10 region upstream of the transcription start site...

Question 19: What sequences are important for the initiation of transcription in eukaryotes, and how does this compare to prokaryotic initiation? What sequence is important for the termination of transcription in eukaryotes, and how does this compare to prokaryotic termination? (There are very specific answers for each of these!)

Classify each statement according to whether it applies to general transcription factors only, specific transcription factors only, both, or neither These transcription factors are found in both prokaryotes and eukaryotes. These transcription factors are proteins. These transcription factors form part of the transcription complex. One of these transcription factors binds directly to the TATA box in the core promoter. These transcription factors bind to the operator. These transcription factors bind to enhancer sequences that may be distant from the promoter....

32P-labeled promoter DNA was mixed, in various combinations, with the general transcription factors TFIID (D), TFIIA (A), TFIIB (B), TFIIF (F), and RNA polymerase II (Pol II). Binding of these factors to the promoter DNA was autoradiograph of the gel is shown below. The anode (+ electrode) is at the bottom. Labels on top of each lane indicate the factors mixed with DNA. For binding reactions 3-7 (lanes 3-7), the concentration of RNA Pol II was continually increased from zero...
